Isaac Newton [1] was the first one in recognizing that the same force that it produces the fall of the bodies toward the earth it also produces the movement of the moon around the earth. In certain sense, it is possible to speak of the graveness like the "invisible rubber" that it maintains together to the universe. When studying with but it details the law of universal gravitation it is possible to obtain the description of the movement of the planets. The laws of the planetary movement developed by Johannes Kepler are deduced from the law of universal gravitation and of the concept of conservation of the angular moment.
